MADE TO BE MADE BY YOU
Because we want to encourage more people to build their own dive kit. Markers are just one starting point: print something personal, learn a new skill and make it your own.
That same curiosity runs through our analyser projects and adapters. We want to help you build, understand and customise your equipment, with more projects to come.
Download the marker files for free and print them yourself. If you would rather have us do the printing, we can make your personalised pack.
